HOISTING- APPARATUS.

Specification of Letters Patent.

Patented Nov. 1 s, 1913.

Application filed April 17, 1912. Serial No. 691,361.

pally in cellars and vaults, in connection with windows or openings in the walls thereof, for hoisting articles up to a position opposite the door or window and then projecting them through or partially through the same Where they are easily accessible from the outer side of the wall.

The object of this invention is to provide a hoisting apparatus for this purpose of ex ceedingly simple and inexpensive construction, which can be readily installed in the vault or cellar, will occupy comparatively little room therein and can be easily operated for hoisting articles therefrom.

In the accompanying drawings: Figure 1 is a side elevation of a hoisting apparatus embodying the invention showing the same installed in a vault o-r cellar adjacent to one of the side walls thereof. Fig. 2 is a fragmentary top plan view thereof partly in section, on an enlarged scale. Fig.

3 is a similar view showing the apparatus turned to project its platform through an opening in the side wall. Fig. 4 is a fragmental-y vertical section on an enlarged 85 scale through the connection for the upper end of the apparatus. Fig. 5 is a similar section through the connection for the lower end of the apparatus. Fig. 6 is a fragmentary cross section in line 6-6, Fig. 1, on an Fig. 7 is a similar section in line 7-7, Fig. 1, on an enlarged scale.

Like reference characters refer to like parts in the several figures.

The hoisting apparatus comprises an up- .right member or column A, a traveling member or carriage B which is mounted on the upright member to slide endwise thereof, and carries a platform or support Z) for the articles to be hoisted, and elevating means for raislng and lowering the traveling member or carriage, which are mounted upon the upright member A. The apparatus is shown arranged adjacent to a wall C of a vault or cellar, which has a window or opening c at its upper edge, and the apparatus is preferably mounted to turn on its supports so that when it has been operated for elevating an article to a position opposite the window it can be turned to project the platform 7) carrying the article into and through or partially through this window.

The upright member or column A preferably consists of a hollow tube or pipe which is held in its upright position by supports or connections which permit it to turn or rotate on its vertical axis. For this purpose any suitable means may be employed. In the construction shown, the lower end of the upright member fits over a tubular bearing portion a and abuts against a shoulder a of a base a? which rests upon the floor of the vault or cellar and has a depending tubular portion a embedded in concrete which also fills the hollow interior of the base and holds the base firmly in place on the floor. The upper end of the upright member A is secured to the ceiling of the vault or cellar by a connecting plate a which is bolted or otherwise attached thereto and has a tubular bearing portion a which fits within the upper end of the upright member, and a shoulder (4 against which this end is adapted to abut. \Vhen there is no suitable overhead support to which the upper end of the upright member can be secured, suitable lateral supports of any kind can be used.

The traveling member or carriage B may be mounted on the upright member to slide endwise thereof in any desirable manner. In the construction shown a guide sleeve 7) is provided which embraces the tubular up right member A and has an open ended slot 7) formed in one side thereof. The platform Z) is preferably of circular shape and may be secured to the guide sleeve b by any suitable means, such as the arms I) I) and the braces 7)" L The inner ends of the arms I) I) embrace the opposite sides of the sleeve I) at its lower end and are secured thereto by screws or other suitable means. These arms are riveted together intermediate of their ends to give them greater strength and rigidity, and have their outer ends spread apart and riveted to the under side of the platform Z). The metal braces 7) Z) are connected at their lower ends to the platform 7) and at their upper ends to the opposite sides of the sleeve 7) at its upper end, screws or rivets being employed for this purpose. The platform is thus rigidly secured to and supported by the sleeve 6. The sleeve 7) is free to slide endwise of the upright memher or column A, but is held from turning thereon by a longitudinal rib or spline D which is bolted or otherwise secured to one side of the column and extends through the slot 6 of the sleeve. This rib prevents the sleeve from turning, but does not interfere with its sliding endwise of the column. Any other suitable means, however, may be employed for this purpose.

The means employed for raising and lowering the carriage may be of any suitable construction, and may be mounted on the upright member in any desirable manner. In the construction shown, a rope or cable E is employed which is secured to the upper end of the sleeve 6 and extends upwardly therefrom over a pulley e suitably journaled in a slot in the upper end of the upright member, and thence downwardly to a winding drum F which is ournaled in a frame f and is operated in the usual manner by a winding handle f on an operating shaft which is geared to the drum shaft. The frame f is secured to the rib D of the upright member by bolts f which extend thrcugl'i the rib and engage the upright member. This frame projects beyond the sides of the rib D, but the radial thickness of this rib is such that the projecting parts of the frame lie outside ofthe path of movement of the sliding sleeve 6 on the upright member and do not interfere therewith.

The entire apparatus is very simple and can be economically and cheaply manufactured. it can be quickly and easily installed wherever desired, as all parts of the apparatus are mounted on a single upright column, and it is only necessary to properly secure this column in its upright position to effect the installation. The upright column being free to turn on its vertical axis enables the apparatus to be turned when desired to project the platform through the wall opening, but the apparatus can be easily held frem turning by the handle until the platform has been elevated to position opposite the door or window, and can then be turned by the handle as far as may be necessary. There is, therefore, no danger of the apparatus turning, so that the platform will strike the wall or swing out of position when being raised or lowered. By sup porting the platform for the article at some distance from the sliding sleeve, it is possible to project. this platform through the window opening, so that the article carried thereby can be readily reached from outside the wall, and the extent to which the platform can be projected depends to a considerable degree upon the distance at which the platform is supported from the sliding sleeve.

I claim as my invention:

1. In a hoisting apparatus, the combination of an upright column of circular crosssection having a longitudinal rib secured to one side thereof, a sleeve which embraces said column and has an open ended slot through which said rib extends, a platform for the article to be elevated supported by said sleeve, and elevating means for said sleeve including a cable and a winding drum therefor, said drum being journaled in 'a frame mounted on said rib, said rib being of sufiicient depth to support said frame out of the path of said sleeve as it is moved up and down said column, substantially as set forth.

2. In a hoisting apparatus, the combination of an upright tubular column'of circular cross-section having journal hearings at the upper and lower ends thereof, said column having a channel bar attached to one side thereof, said channel bar having its open side turned toward the column and being nally thereof, a frame having a back and side members, the back of said frame being secured against the outer face of said channel bar, a hoisting drum journaled between the sides of said frame, a sleeve slidably mounted on said column and having an open-ended slot therein, the side walls of said slot approaching the sides of said channel bar, a load supportin platform attached to said sleeve, said column having a slot formed therein near the upper end thereof, a sheave journaled in said slot, and a cable attached to said sleeve, passing over said sheave and wound on said drum, substantially as set forth.

Witness my hand this 15th day of 1912. Y
